Abstract
A method and system for generating a modified and enhanced dissolved tire rubber bitumen compound are described. The method includes receiving an rapid digestion process (“RDP”) compound, a bitumen compound, and a sulfur cross-linking agent. First heating the RDP compound, the bitumen compound, and the sulfur cross-linking agent to 320° F. to 420° F. with mixing for 3 to 5 hours. The method then proceeds to add SBC to the RDP compound, the bitumen compound, and the sulfur cross-linking agent. The RDP compound, the bitumen compound, the sulfur cross-linking agent, and the SBC are second heated to 320° F. to 420° F. with mixing for 15 minutes to 120 minutes.
Claims11
A method for generating a modified and enhanced dissolved tire rubber bitumen compound comprising:
- receiving a rapid digestion process (RDP) compound, wherein the RDP compound is selected from the list consisting of an unmodified RDP compound, a modified RDP compound, an enhanced RDP compound, and a modified enhanced RDP compound;
- receiving a bitumen compound;
- receiving a sulfur cross-linking agent;
- first heating the RDP compound, the bitumen compound, and the sulfur cross-linking agent to 320° F. to 420° F. with mixing for 3 to 5 hours;
- adding a Styrenic Block Copolymer (SBC) to the RDP compound, the bitumen compound, and the sulfur cross-linking agent;
- and
- second heating the RDP compound, the bitumen compound, the sulfur cross-linking agent, and the SBC to 320° F. to 420° F. with mixing for 15 minutes to 120 minutes to generate the modified and enhanced dissolved tire rubber bitumen compound.
